Pressure plate? Yeah, you can get away with aligning (centering) it by eye and then tightening the bolts that hold it to the flywheel up.
It's worth noting that its a pull-type clutch which means;
a)You have to remove the slave cylinder on to of the gearbox before you can separate the gearbox from the engine.
b)When refitting the box, you have to lace the release bearing on the input shaft of the gearbox and latch (engage) it with the fork. You then bolt the gearbox to the engine and then, with a firm smack, lock the release bearing into the pressure plate by moving the clutch lever.
